Geophysical Data for Assessment of Karst Drainage Features in Genesee County, New York Geophysical Data for Assessment of Karst Drainage Features in Genesee County, New York
In September and November 2023, the U.S. Geological Survey, in cooperation with the New York State Department of Environmental Conservation, collected geophysical surveys of 5 karst drainage features (sinkholes) in eastern Genesee County, New York, in order to study the nature of the subsurface fill material, bedrock topography, and karst dissolution features. Sites were surveyed using...
Puerto Rico new radiometric age analyses Puerto Rico new radiometric age analyses
This dataset contains U-Pb isotopic data and associated ages of zircons from selected igneous rocks collected from the region surrounding and including the uplands of the United States Territory of Puerto Rico. The samples were collected as part of geological mapping and research conducted during 2018 and funded by the Mineral Resources Program of the U.S. Geological Survey. Zircon...

Lunar Grid Reference System (LGRS) Terrestrial Navigational Training Grids in Artemis Condensed Coordinate (ACC) Format Lunar Grid Reference System (LGRS) Terrestrial Navigational Training Grids in Artemis Condensed Coordinate (ACC) Format
USGS is assessing the feasibility of map projections and grid systems for lunar surface operations. We propose developing a new Lunar Transverse Mercator (LTM), the Lunar Polar Stereographic (LPS), and the Lunar Grid Reference Systems (LGRS). We have also designed additional grids to meet NASA requirements for astronaut navigation, referred to as LGRS in Artemis Condensed Coordinates...
